Bringing your services and/or products directly to your clients saves them time and money.

If you’re willing to take on some risk and have the heart of a true hustler, you can make extra money online doing commission-only sales for startups and other businesses. While you won’t be getting a regular salary, with the right sales strategies and skills as an inside sales rep, you can make decent money for each sale you bring in. And because you’ll most likely be working with startups, if you can negotiate a little equity you could profit big time if you're pitching a solid product and the startup succeeds.
Freelancing is the next best thing to being paid more for your full-time work, because professional work always pays more than unskilled. To find opportunities, let former colleagues or other personal connections that you’re available for freelance gigs. (Here are some ideas on how LinkedIn could be useful for that.) Or, post on marketplaces particular to your field. For instance, Mediabistro, a journalism site, allows freelancers to post profiles of their experience and services. Though these are more up to chance, designers can bid on jobs at 99Designs.com or submit a design at Threadless, to see if it will be crowdfunded. Elance-Odesk also lists many freelance opportunities, and you can also post your own services on Fiverr, although some freelancers say these services create a race to the bottom on fees and so are not very lucrative. If you're new to freelancing, here's how to set your rates, and here's how to negotiate raises with clients.
Big companies are generally (or at least should be) flexible if you want to work from home a few days a week. But if you want to do it full-time, smaller companies can be a better bet, because your working remotely can help them save on office space.

Notice the "may be".

They are however, legitimate businesses rather than "make money in your sleep" or any of those other phony work from home schemes.
I may as well start with something I know well. When I started out as a freelance writer 20 years ago, things were very different. I wrote mostly for magazines, and I had to rely on snail mail to send out drafts and queries. I’d wait weeks for a response from my editors. Not many people had the patience for it, and few stuck around long enough to ever start earning a real income from it.
Use your home to work from home. If you live in an area where there is a demand for short-term rentals (like near a university or the downtown of a large city), you may well be able to find renters by networking in your community. However, with the rise of Airbnb and places like it the Internet has once again made it much easier to make money from home. Using these sites you can rent out a private room, shared room or even your whole house for a night or month or whatever period of time you like.
Freelance writers can more easily be thought of as a “writer for hire” or someone who is contracted out to write about a particular topic. If you have some writing chops, but don’t want to deal with all the extra work that goes into running a blog, you can hire yourself out and write for newspapers, large online publications and even other bloggers.
If you own a camera, starting a freelance portrait photography business could be a very natural way to turn your skills and passions into a profitable business idea.

Not to be confused with hoarding, this business idea takes a lot of time, patience, and passion. If you have an eye for good art, it’s easy to get in on the ground level by visiting the studio department at your local university—though don't expect to get rich overnight with this side business idea. Many art students are more than happy to sell their work for a bargain, and in as little as a few years, there's a chance that piece you bought for a couple hundred bucks may be worth well into the thousands. Beware though, this business idea will take a whole lot of patience (and storage space for all that art).
Babysitting isn’t just for teens. Everyone from college students to recent retirees can make money watching other people’s children. Word-of-mouth referrals from friends and family are still a great way to get started, but you can also create a profile on Care.com or Sittercity to expand your reach. Note any specialized skills, such as CPR certifications or experience with special needs children, to make yourself more marketable.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt).
